To fzZZ whom t may con com Be it known that I, JAMES R. Picentino, a

citizen ot the United States, and a resident ot Scranton, in the county of Laclravvanna and State ot' Pennsylvania, have invented certain new and usct'ul improvements in Mining-Car Trucks, of which the 'following is a full, clear, and exact description. A rThis invention relates to car and truck mountings and in particular to mine cars wherein the body of the car is carried on a journal box in which the axle revolves.

A particular object of the invention is the provision or' a construction that will allow of 4the body or the car being brought closer to the ground so that the miner will not have to lift his load so far each time in fillingr the car.

Another-object is to provide a bearing plate, which, While being formed to allow of lowering the car body Will also be prevented from slipping endwise.

Another object is the provision ot' means ou the bearing member which will allow the journal box to be self-aligning,

figure 2 is a section in elevation taken on the line 2-2 of Figure l, and shows the method of fastening the journal box to the bearing plate.

h ground, the sill is cut out seml-circularly l5 to receive the bearing plate 14.- which is shaped at its center to conform with and possible relatively to the 13 thereof ht snugly into said cuteout 15. The bear- 60 ing plate is cast to comprise extensions 16 through which pass the bolts 1r through the' medium of which the bearing plate is retained in position against the sill 13.

rllhe bearing plate is also cast to com- 05 prise oppositely disposed crutches 18 1ocated adjacent the edges of the semi-circular part thereof and into which extend the side tianyres 25 formed/on the journal box 12.

The journal box 12 comprises essentially 7.0 a cylindrical casting through which extends an axle receiving bore 19, and in which is formed an interior cylindrical recess 20 within which are disposed the roller bear- I ings 21 between the journal box is the cylindrical liner 22, the latter of which is used to prevent wear of the inner surface of the journal box by the bearings.

"he endof the journal box is closed with a cover 231 which is the lubricant within the journal box,

The side flanges 25 are cast integral with. the journal box and extend a istance equal 85 to the Width of the bearing plate, terminating at their outer ends in lips 26 which are also castl integral with the journal box and ear against the outer edge of the bearing plate vlet at the points Where the crutches 18 uw are formed therein. y

It will be noted that the flanges 25 have up and in the crutches, and that that unthe'semirrcular indentation in said bearing plate. This construction provides a selfaligning journal box and the weight of the roo car is transmitted through said knob to the roller bearings 21.

The roller bearing recess 20 is provided in the lower portion thereof with a channel 27 disposed centrally thereof which constitutes roe a lubricant holding chamber, lubricating oil is fed through th 28 which is normally closed by plug 29; The outer end of the to provide an enlarged opening() vhich e opening the screw and which n' i journal box is formed im' cast to provide an exterior .i ing being lubricant can be forced into the g Y Y y1,451,690

4receives the hub ofthe wheel l0, said openrovided with an inset packing land 31. buitable wear washers 32 may be inter osed between the inner face ofthe hub and t ie journal box. An additional packing gland 33 is provided in the journal box between the opening 30 therein and the bearing recess Q0 ,to prevent' the lubricant from greping out along the axle 1l to the wheel 4In ordrto provide the filling of the lubricant chamber withoiit'r1 going behind the w/heels of the car asis required in using the opening 28, it will be noted upon reference to Figures 3 and 4 that the journal box is l 3l which extends from a point adjacent the outer end of said journal box to a point near the lubricant chamber, and which is bored as at said bore opening directly into tliejreservoir or chamber 27. With this arrangement the chamber frombetween the spokes of the wheel.

It can thus be seen that in this construction, the car is lowered appreciably more than in the case where a plain straight bearing plate is used. Also there is provided a self-aligning journal box which is essential in` this type of car to maintain even wear `on the parts as'the tracks of mines are usually crooked and present a rough path over which the cars must travel.

Claims.
